Bowman produced these beautifully painted trading cards beginning in 1951: Jets, Rockets, and Spacemen! The “jets” cards merely showed normal airplanes with informative text on the back, but the rest of the series told a story about a fantastic space adventure, with each card as a chapter.

Though I only heard about these cards this year, the series is clearly a direct ancestor of the Meteor Mags stories. Its conception of space involves pirates, cats, octopuses, and dinosaurs (flying reptiles, actually: pteranodons). That’s my kind of space adventure!
